DEVICE FOR SECURING BRAKE-HEADS TO BRAKE-BEAMS.

SPECIFICATIGN forming part of Letters Patent No. 441,195, dated November 25, 1890.

Application filed September 5,1890. Serial No. 364,034. (No model.)

To all whom it may concern:

Be itknown that I, HENRY 15. ROBISCHUNG,

a citizen of the United States, residing at Kalamazoo, in the county of Kalamazoo and State of Michigan, have invented certain new and useful Improvements in Devices for Securing Brake-Heads to Break-Beams; and I hereby declare the following to be a full, clear, and exact description of the same, refer.- ence being had to the accompanying drawings, in which- Figure 1 is a plan view of a metallic brakebeam, portions broken away, together with supplemental attaching-blocks embodying my invention, brake-heads, and shoes, the attaching-blocks, brake-heads, and shoes being in section. Fig. 2 is a side view of the supplemental attaching-block, brake-head, and shoe. Fig. 3 is a detached view of the brakehead and shoe. Fig. 4 is a transverse section of the brake-head and shoe on the line a; m, Fig. 3. Fig. 5 is a rear plan vieW of the brakehead. Fig. 6 is a face view of the attachingblock and face-plate. Fig. 7 is alongitudinal section of the supplemental attaching-block and its face-plate on the line y y, Fig. 6. Fig. 8 is a plan view of the clamp. Fig. 9 is a transverse section of the clamp on the line 5 2, Fig. 8. Fig. 10 is a View of a combined clamp and bolt which may take the place of the separate clamp and bolt.

Like symbols refer to like parts wherever they occur.

My invention relates to the construction of supplemental attaching-blocks for the purpose of enabling brake-heads of the forms commonly used with wooden brake-beams to be fitted to and used with metallic brakebeams.

Heretofore the common form of brake-beam has been the wooden brake-beam of general rectangular cross-section, and the most approved forms of brake-heads have been provided with rectangular beam recesses (see Fig. 3) .and lateral flanges for securing the head to the beam. At present trussed metallic break-beams, which are much smaller and of very different cross-sectional form, are coming into use, rendering the common and approved patterns of brake-head useless unless special provision is made for attaching the said brake-heads to the metallic beams.

The object of the present invention is to provide a simple, secure, and effective means for such purpose, and is especially directed to providing for that class of brake-heads which as at present used with wooden beams are each secured to the beam by a single centrallyplaced bolt; and to this end the invention, broadly stated, consists in the combination of an attaching-block having a face or bearing plate with looking flange or lug to receive the lateral flanges of the common forms of brake-head and a clamp for securing the flange of the brake-head to the face-plate of the attaching-block, substantially as Will hereinafter more fully appear.

I will now proceed to describe my invention more fully, so that others skilled in the art to'which it appertains may apply the same.

In the drawings, A indicates the beam, B the post or strut, and C the tension-rod or truss-rod, of any approved form of metallic beam, the particular construction being immaterial, as the same forms no part of the present invention.

1 indicates the supplemental attachingblock of general cup or equivalent form, adapted by its shape and form to receive or embrace the end of the metallic beam A, and secured thereto by the ends of the truss-rod and the nuts thereof, as in the instance chosen for illustration, or in any other suitable manner, as the case may require.

Attached to or formed with the supplemental attaching-block 1 is a face-plate, bearing-plate, or table 2, correspondingin general form and adapted to receive the back plate or laterally-projecting flanges a "a. (see Figs. 4 and 5) on the back of the common form of brake-head, one end of said face-plate 2 being provided with overhanging lugs or an undercut flange, as at 3, While the opposite end has a bolt-hole 4E, and may, if desired, have a rib 5 to form a brace for the clamp 6, which 00- acts with the face-plate 2'. 6 indicates aclamp provided with an overhang 7, adapted to bind on the opposite edge of flange CL of the brake-head from that which takes under the lugs or undercut flange 3 of the supplemental attaching-block, and said clamp may be bound to the face-plate by a bolt 8, separate from or integral with the clamp 6, (see .Fig. 10,) or by other suitable means.

When in use, the supplemental attachingblocks 1 are secured to the metallic beam, as hereinbefore explained. One edge of the back plate or flange a of the usual brake-head is inserted under the lugs or undercut flange 3, the clamp 6 is applied on the opposite end of flange a, and the head bound firmly to the face-plate 1 or table by'the bolt and nut or other suitable means.

In addition to the advantages of strength and simplicity, a construction substantially such as herein described has the advantage of facilitating the removal and replacing of the brake-head on inside-hung brakes, as the only fastening to be removed is the clamp 6 and its bolt, which are to the outside of the brake-head, at the outer end of the beam.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, isy p 1. A supplemental or attaching block for brake-beams, said block having a face-plate or table for the reception of the back plate of the common form of brake-head, and a clamp forbinding the back plate of the brakehead to the face-plate of said attaching-block, substantially as specified.

2. The combination, with a supplemental attaching-block for brake-heads, said block having a transverse face-plate or table With undercut lug or flange at one end, said faceplate and its end flange adapted for the reception of the back plate of the common form of brake-head, of an undercut clamp-block adapted to be secured to the opposite end of said face-plate, substantially as and for the purposes specified.

3. A supplemental attaching block for brake-beams, said block havinga cup or beam socket, a face-plate or table parallel with the axis of the socket, and a clampsection adapted to bind the back plate of a brakehead to the face-plate or table of the supplemental attaching-block, substantially as and for the purposes specified.

In testimony whereof I afiiX my signature,

in the presence of two witnesses, this 30th day 7 of August, 1890.
